Generally, acupoints are in the cracks of bones. If they are not in place, it is impossible to press them with your fingers. You can buy a scraping board and press it with its edge, which will make you more sensitive when pressing the right acupoints. Generally speaking, after pressing the acupoints, you will feel numb, swollen and sour. Go to see the video of the people in China, which is very detailed about the meridians.
